Segmentation fault (core dumped) on Ubuntu (3.30.0)

[an0n.r00t32]

i reported yesterday with a bug of wxWidget, i tried this version: wxWidgets-WX_3_0_BRANCH and recompile filezilla 3.30.0, it gave me the error

[Tim Kosse]

Please post a stacktrace.

[an0n.r00t32]

where to find the stacktrace for it?

[Tim Kosse]

Make sure to has been compiled with debug symbols (should be the default) and run it in your favorite debugger. Any debugger will automatically stop execution if a segfault happens, allowing you to then generate a stacktrace, or backtrace as it is sometimes called.

here i used gdb

[an0n.r00t32]

please help me fix this :(

[Tim Kosse]

That's odd. There's no segfault reported in gdb when running FileZilla. Can you confirm that it crashed?

[an0n.r00t32]

when i executed "filezilla" as command, it gave me "reading locale filezilla.xml" then core dumped, thats all i got

[Tim Kosse]

Did you remove the previous version or is it still lying around?

[an0n.r00t32]

can u show me how remove the prev one completely? i just replaced it by recompiling then i will let u know if it works or not, thanks

[Tim Kosse]

That depends how the previous version, or versions, were installed. If you used 'make install', then you need to remove all installed files by hand [1]

If you installed FileZilla using your system's package manager, it needs to be removed there.

[1] For this reason I always use custom installation prefixes added to PATH, LD_LIBRARY_PTAH and PKG_CONFIG_PATH, if anything goes wrong, the entire prefix can be deleted.

[an0n.r00t32]

man! useless :( i removed every files and recompiled :( didnt work either, can u fix it on the next release?

this is wat i got after recompiling, the same like previous one

[Tim Kosse]

can u fix it on the next release?

No, not without a stack trace. All I know to this point is that there's something wrong. What's missing is what is wrong.

[an0n.r00t32]

i just reinstalled my linux, and compiled it again, this time it worked :| dunno why
